Abstract
AIM: This study aimed to investigate the association between work patterns and periodontal disease. MATERIALS AND METHODS: Data were collected from the Korea National Health and Nutrition Examination Survey between 2007 and 2012, and data from 22,508 subjects aged ≥19 years were included. An individual's work pattern was classified as either daytime or shift work. Sleep duration was categorized into three ranges: ≤5, 6-8, and ≥9 hr/day. A multivariate logistic regression model was used to determine the adjusted odds ratio for CPI ≥3. The CONTRAST statement was used to show the interaction effect of work patterns and sleep duration. RESULTS: The adjusted OR of shift work was 2.168 (CI: 1.929-2.438, P<0.0001). Participants who sleep ≤5 or ≥9 hr/day showed ORs 0.735 and 0.663, respectively (P=0.0181). The interaction effect analysis revealed that the work pattern had a strong influence on periodontal condition when combined with sleep amount. Shift workers with ≤5 or ≥9 hr sleep showed significantly increased ORs for CPI ≥3 (2.1406 and 2.3251, respectively, P<0.0001). The ORs for daytime workers were comparable to the original values (≤5: 0.7348, P=0.0292; ≥9: 0.6633, P=0.0428). CONCLUSION: Altered sleep patterns caused by shift work have more influence on periodontal disease than sleep duration. This article is protected by copyright. All rights reserved.
